This creates a problem for fish farming applications.\u003c\/p\u003e\u003ch3\u003eCarbon Dioxide as CO\u003csub\u003e2\u003c\/sub\u003e test kit\u003c\/h3\u003e \u003cp\u003e\u003cbr\u003e Carbon dioxide can be measured quickly and safely with the HI 3818 carbon dioxide test kit. This compact, portable kit allows the user the option of field or laboratory use. The design makes the kit easy to handle and, except for the Carbon Dioxide reagent, practically prevents accidental injury or damage due to spills.\u003cbr\u003e\u003cbr\u003e Carbon dioxide (as carbonic acid) in the water sample is neutralised with a dilute sodium-hydroxide solution to a pH of 8.3 using a phenolphthalein indicator.
